embodies the essential characteristics of strength and rigidity with a minimum increase of cost and labor as compared to similar hods in which but a single bottom is present and which are extremely liable to become damaged in placing such heavy material as coal therein.

In one of the bottom sheets of my hod I .1 all whmn it may concern: I Be it known that I, GEORGE J. DUFFETT, a j citizen of the United States, residing in the city of St. Louis, in the State of Missouri, l have invented certain new and useful Im provements in Coal-Hods, of which the foli lowing is a full, clear, and exact description, 1 reference being had to the accompanying' drawings, forming part of this specification. form one or more perforations.
